Abstract
The invention belongs to technical field of pesticide, disclose a kind of rice blast acid amides water dispersible granules, its component content is by percentage to the quality: rice blast acid amides 10%~80%, wetting agent 3%~12%, dispersant 3%~12%, disintegrant 0%~10%, binding agent 0.1%~3%, filler 5%~84%.Above components in certain proportion is mixed, after stirring, obtain female powder, female powder and binding agent are mixed through pulverizing, granulation then, oven dry, sieving obtains rice blast acid amides water dispersible granules.This invention has overcome the shortcoming of suspending agent and wetting powder, has reduced the pollution to environment, is mainly used in the control rice blast.
Description
Technical field:
The invention belongs to technical field of pesticide, be specifically related to a kind of rice blast acid amides water dispersible granules.
Background technology:
Rice blast acid amides (fenoxanil) is the acid amide fungicides of the common exploitation of BASF and Japanese agricultural chemicals company, chemical name N-(1-itrile group-1,2-dimethyl propyl)-2-(2,4 dichloro benzene oxygen base) propionamide, and structural formula is:
The rice blast acid amides is inhaled and residual activity in having well, is the melanin biosynthesis inhibitor.Be used to prevent and treat rice blast, to crop, mammal, Environmental security.
Rice blast is one of paddy rice three big important diseases, is distributed widely in each rice district, the world, and all there is generation in various degree every year in China north and south rice district, and is heavier with the morbidity of southern mountain rice field especially.The paddy rice whole growing all can be fallen ill, because the period of causing harm is different with the position, can be divided into seedling pest, leaf pest, joint pest, ear stem pest and grain pest, and wherein general with the generation of leaf pest, the stem pest cause harm the heaviest.But the underproduction 40%~50% when serious takes place in disease, even No kernels or seeds are gathered, as in a year of scarcity.
At present, product forms on the rice blast acid amides market is a suspending agent, though suspending agent belongs to the environmental protection preparation, but its bin stability is important performance indications, it concerns the performance and the effect of product, and the factor of influence stability is more, requires all higher to former concentration, auxiliary agent, pH value, and suspending agent placed and occurred layering or deposited phenomenon for a long time easily, and then influenced the performance of drug effect.Water dispersible granules has had the advantage of suspending agent product concurrently, has overcome its shortcoming, is one of emphasis formulation of pesticidal preparations formulation development.
Summary of the invention
The objective of the invention is in order to overcome the suspending agent product stability problems, proposed a kind of environmental protection, be convenient to transport, availability height, rice blast acid amides water dispersible granules easy to use.
The present invention is achieved by the following technical solutions:
The present invention relates to a kind of rice blast acid amides water dispersible granules, it is characterized in that: its composition contains following percentage by weight: rice blast acid amides 10%~80%, wetting agent 3%~12%, dispersant 3%~12%, disintegrant 0%~10%, binding agent 0.1%~3%, filler 5%~84%.
Described dispersant is selected from one or more in polycarboxylate, lignosulfonates, alkylphenol polyoxyethylene formaldehyde condensation products sulphate, naphthalene sulfonic acid-formaldehyde condensation product sodium salt, alkylphenol polyoxyethylene, aliphatic amine polyoxyethylene ether, polyoxyethylene carboxylate, the fatty acid glyceride APEO; Described wetting agent is selected from lauryl sodium sulfate, draws back powder, among the wetting and penetrating agent T, spaonin powder one or more; Described disintegrant is selected from one or more in ammonium sulfate, calcium chloride, urea, magnesium chloride, aluminium chloride, citric acid, succinic acid, the carbonic hydroammonium; Described adhesive is selected from one or more in polyethylene glycol, polyvinyl alcohol, xanthogenic acid glue, carboxymethyl cellulose, polyvinylpyrrolidone, crospolyvinylpyrrolidone, the white dextrin; Described carrier is selected from one or more in kaolin, diatomite, starch, talcum powder, mica powder, glucose, bentonite, the precipitated calcium carbonate.
Rice blast acid amides water dispersible granules of the present invention is to produce by following steps:
The former medicine of rice blast acid amides is obtained the particle diameter that needs with dispersant, wetting agent, disintegrant, filler through comminution by gas stream, add adhesive again, obtain the materials of granulating.It is interior through after granulation and the drying to expect that product are quantitatively sent the fluidized bed granulation dryer to, obtains its water dispersible granules product.
Rice blast acid amides water dispersible granules of the present invention is mainly used in the control rice blast.
The invention has the advantages that: it is simple to have production technology, cost is low, and is easy to use, operator ' s health do not had characteristics such as injury and environmentally safe, reduced cost, improved safety to the producer, transporter, user, while content height of the present invention, disintegration rate is fast, good dispersion, and can give full play to the drug effect of rice blast acid amides, and strengthened penetrating ability to plant disease, improved the availability of effective active composition.
